Degree of synergistic effects and conflicts according to WFD aims
The restoration of an intertidal wetland can attribute to 4 main pressures in the mesohaline zone of the Scheldt. However, Ketenisse is only a small scale pilot project (60 ha). The real effect of Ketenisse to the Scheldt estuary is hence minimal. The real objective of Ketenisse was also the research aspect. Small scale projects were studied to learn more about the creation of an optimal starting condition for the development of valuable intertidal wetlands.| Indicator Group | Code | Main pressures mesohaline zone Scheldt | Effect? | Description | ||||
| - | 0 | + | ||||||
| S.I. | 1.1 | Habitat loss and degradation during the last about 100 years: Intertidal | x | A former intertidal brackish marsh located in an industrial area is expanded by management realignment. | ||||
| S.I. | 1.5 | Gross change of the hydrographic regime during the last about 100 years | X | At larger scale, a intertidal wetland can contribute to the hydrographic regime of the estuary (eg. water storage capacity and safety function) | ||||
| S.I. | 3.1/3.2 | Decrease of water and sediment chemical quality | X | The sediment at Ketenisse was already highly contaminated and hence improving the quality is difficult. | ||||
| D.I. | 1.3 | Land claim during the last about 100 years | X | A former intertidal brackish marsh located in an industrial area is expanded by management realignment. | ||||
| D.I. | 1.7 | Relative Sea Level Rise | X | Adjacent land is given back to the estuary. A larger estuary is more dynamic to manage extreme events and disturbances. | ||||
